Question about bit fields

[puni2k]

Hi there,

I'm currently in the process of creating a config file for my Wolf CHA-10 and am stuck at a problem on how to handle bit fields.
There is one message that returns on/off information for various items like pumps, valves...

In the value returned i.e. Bit 0 shows if pump 1 is running, Bit 1 is for pump 2, Bit 11 is for one of the electric heaters...

How would I define this message in my config?
I tried it with this but i noticed that I can only use BI0-7 as data types.

r,cha,cha08,CHA Statusfelder,,8,5022,CC7930,heizkreispumpe,,BI0,0x00=Aus;0x01=Ein,,Heizkreispumpe,zubringer_heizkreispumpe,,BI1,0x00=Aus;0x01=Ein,,Zubringer-/Heizkreispumpe,3_wege_hz_ww,,BI2,0x00=Aus;0x01=Ein,,3-Wege-Umschaltventil HZ/WW,3_wege_hz_k,,BI3,0x00=Aus;0x01=Ein,,3-Wege-Umschaltventil HZ/K,ausgang_a1,,BI4,0x00=Aus;0x01=Ein,,Ausgang A1,e_heizung,,BI5,0x00=Aus;0x01=Ein,,E-Heizung,verdichter,,BI6,0x00=Aus;0x01=Ein,,Verdichter,ausgang_a3,,BI8,0x00=Aus;0x01=Ein,,Ausgang A3,ausgang_a4,,BI9,0x00=Aus;0x01=Ein,,Ausgang A4,e_heizung_phase_1,,BI10,0x00=Aus;0x01=Ein,,E-Heizung Phase 1,e_heizung_phase_2_3,,BI11,0x00=Aus;0x01=Ein,,E-Heizung Phase 2 und 3

So would i rather expand the number of fields to 16, re-sort the fields according to the position in the bit field and use BI7 as data type?
